ReactOS has achieved a substantial milestone with the synchronization of its MSVCRT implementation with Wine 10.0, marking progress toward Windows NT6 compatibility. This development signifies a meaningful reduction in test failures and improved application support within the platform.
Key Advances
- ReactOS synced MSVCRT with Wine 10.0 as of the 2026 rollout.
- This synchronization resolved approximately 7,574 out of 25,517 test failures, equating to a 29.6% improvement.
- The changes reduced API test failures by around 30%.
- The rebase was developed over several months and regarded as pivotal for NT6 compatibility.
- The ReactOS project turns 30 in 2026, marking this as a key initiative during its anniversary year.
Development Implications
This synchronization is a modest but meaningful enhancement for ReactOS, as it brings their system closer to the compatibility standards of Windows NT6. By resolving a substantial number of test failures, ReactOS has effectively improved its stability and application support capabilities. This improvement may provide a tailwind for broader adoption and development efforts around the platform.
